A close up of one of the columns being wired to explode inside the old Great Western Sugar Factory in Eaton shows the shaped charges on the outside of the column. Inside the column, attached to the east side is the dynamite that will cause the building to fall. The middle columns on the first floor are being taken out, which will cause the top two floors to colapse.
